3. Create a Venn diagram or Table with numbers for: A group of 80 students were asked if they were taking science or art.
10 were taking neither, 50 were taking science, 30 were taking art.

10 students were taking science and art at the same time.

Step-by-step explanation:

Given that a group of 80 students were asked if they were taking science or art, of which 10 were taking neither, 50 were taking science, and 30 were taking art, to determine how many students take both science and art, the following calculation must be done:

80 - 10 = 70

50 - 30 - 70 = X

80 - 70 = X

10 = X

Therefore, 10 students were taking science and art at the same time.

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
